Shenzhou I Experimental Spacecraft
“神舟一号”飞船
Nov. 20, 1999, China successfully launched Shenzhou I experimental spaceship on a LM-2F launch vehicle in Jiuquan Satellite Launch Center, which laid solid foundation for realizing the strategic target for manned space flight. Four orbital test flights of the Shenzhou spacecraft were conducted without crews. Remained in orbit for 21 hours, it made 14 0rbits around the Earth carrying a dummy astronaut, experimental seeds, national flags and a banner with signatures of participating engineers and scientists and after that the descent module lands in central Inner Mongolia Autonomous Region the next day.
神舟一号飞船是中华人民共和国载人航天计划中发射的4艘无人飞船的第一艘实验飞船。飞船于1999年1 1月20日在酒泉航天发射场成功发射，承担发射任务的是在“长征2号”捆绑式火箭的基础上改进研制的“长征2号”F载人航天火箭。飞船携带一个飞行员模型、一些实验种子，国旗和一面带有航天工程师和科学家签名的横幅绕地球飞行14圈后，顺利降落在内蒙古中部地区的着陆场，飞船在太空中共飞行了21个小时。
The unmanned spacecraft consists of orbit, descent and propulsion modules. The orbit module is the place where astronauts live and work. The descent cabin lies in the middle of the spaceship, and is the astronauts cabin and the command and control center. It is a airtight structure with a hatch on the top for astronaut to get in and out of the descent cabin and enter the orbital module, and it is the only landing part of the spaceship to return into the air and to land on the earth. In advancement spacecraft has two solar cell wings, attached to the outside of the instrument propulsion module below the descent cabin. The two solar cell wing total area of 24.48 m2, which are deployed after launch and supply the power distribution. Shenzhou I experimental spaceship is the important milestone in China's spaceflight history.
飞船由轨道舱、返回舱和推进舱组成。轨道舱位于飞船的前段，通过舱口与后面的返回舱相通，轨道舱是宇航员在轨飞行期间的生活舱、试验舱和货舱。飞船中部的返回舱是飞船的指挥控制中心，航天员乘坐其上天和返回地面。推进舱位于飞船的后部，主要用于飞船的姿态控制、变轨和制动。除此之外，推进舱两侧装有20多平方米的主太阳能电池阵。飞船发射后两侧太阳能电池阵机翼打开为前进中的飞船提供电力。“神舟一号”无人试验飞船是中国载人航天工程的首次飞行，标志着中国在载人航天飞行技术上有了重大突破，是中国航天史上的重要里程碑。
